Answers:
1. TCP Port 179 is used to create and maintain BGP adjacencies.
2. "B". When an RR receives a routing update from an RR client, the route is then advertised to both clients and nonclients.
3. "D". The BGP attribute weight is locally significant only.
4. "B". That's an indication of a potential routing loop, so the update will not be accepted.
5. We could configure confederations or route reflectors.
6. "C". The route with the highest local preference will then be preferred.
